1、php采用安全线程模式进行编译 –enable-maintainer-zts必须加上
configure_options=" '–prefix=/usr/local/php' '–with-config-file-path=/usr/local/php/etc' '–enable-fpm' '–with-fpm-user=www' '–with-fpm-group=www' '–with-mysql=mysqlnd' '–with-mysqli=mysqlnd' '–with-pdo-mysql=mysqlnd' '–with-iconv-dir' '–with-freetype-dir=/usr/local/freetype' '–with-jpeg-dir' '–with-png-dir' '–with-zlib' '–with-libxml-dir=/usr' '–enable-xml' '–disable-rpath' '–enable-bcmath' '–enable-shmop' '–enable-sysvsem' '–enable-inline-optimization' '–with-curl' '–enable-mbregex' '–enable-mbstring' '–with-mcrypt' '–enable-ftp' '–with-gd' '–enable-gd-native-ttf' '–with-openssl' '–with-mhash' '–enable-pcntl' '–enable-sockets' '–with-xmlrpc' '–enable-zip' '–enable-soap' '–with-gettext' '–disable-fileinfo' '–enable-opcache' '<span style="color:#ff0000;">–enable-maintainer-zts'</span>"2、安装pthreads 下载路径为 https://github.com/krakjoe/pthreads php7版本采用V3，php5.3以上版本采用V2。
编译安装成功之后，，增加 extension=pthreads.so
重启nginx和php-fpm，提示Starting php-fpm Failed loading /usr/local/zend/ZendGuardLoader.so: /usr/local/zend/ZendGuardLoader.so: undefined symbol: executor_globals done这是由于php在安全线程模式下运行不支持ZendGuardLoader的原因，可以直接无视。
3、下面感受一下多线程的效率
<?phpclass test_thread_run extends Thread {public $url;public $data;public function __construct($url){$this->url = $url;}public function run(){if(($url = $this->url)){$this->data = model_http_curl_get($url);}} } function model_thread_result_get($urls_array) {foreach ($urls_array as $key => $value){$thread_array[$key] = new test_thread_run($value["url"]);$thread_array[$key]->start();}foreach ($thread_array as $thread_array_key => $thread_array_value){while($thread_array[$thread_array_key]->isRunning()){usleep(10);}if($thread_array[$thread_array_key]->join()){$variable_data[$thread_array_key] = $thread_array[$thread_array_key]->data;}}return $variable_data; } function model_http_curl_get($url,$userAgent="") {$userAgent = $userAgent ? $userAgent : 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.2)';$curl = curl_init();curl_setopt($curl, CURLOPT_URL, $url);curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);curl_setopt($curl, CURLOPT_TIMEOUT, 5);curl_setopt($curl, CURLOPT_USERAGENT, $userAgent);$result = curl_exec($curl);curl_close($curl);return $result; } for ($i=0; $i < 100; $i++) {$urls_array[] = array("name" => "baidu", "url" => " wd=".mt_rand(10000,20000)); } $t = microtime(true); $result = model_thread_result_get($urls_array); $e = microtime(true); echo "多线程：".($e-$t)."\n"; $t = microtime(true); foreach ($urls_array as $key => $value) {$result_new[$key] = model_http_curl_get($value["url"]); } $e = microtime(true); echo "For循环：".($e-$t)."\n"; ?>多线程：0.9154269695282 For循环：5.3936388492584
